So, they are now blink in recommendations, we can't say you should get pregnant before you are 35 or before you are 38, but what couples really do need to understand is they need to understand the information. Infertility is inability to conceive or carry a pregnancy despite 12 months of unprotected intercourse. So, we know that 88% of couples in the United States who attempt pregnancy for 12 months will conceive and will be able to deliver. The remaining 12% were about 6 to 6.2 may be million couples in the United States have problems in conceiving. And they are defined as sub fertile or infertile.

Female Speaker: How fertile anyone couple may be is a complicated equitation with genetics, physiology, lifestyle, environment, and age all playing a role. And though doctors examine all male and female fertility issues, unfortunately not all couples will be able to conceive. Despite the best medical science has to offer. Still experienced fertility counseling may be a couple's best chance for success.
